Delancey Underground, affectionately dubbed the "Low Line" is a proposed two-acre park that would transform an abandoned trolley terminal beneath Delancey Street on the Lower East Side into a functioning green space complete with an expansive lawn, benches, and reflecting pools.

The park would use state-of-the-art solar technology to filter in sunlight from above to allow subterranean plant growth without exposing visitors to harmful ultraviolet and infrared rays.

The ambitious underground oasis is still in the theoretical stages but already has New Yorkers buzzing with excitement. Initial plans were reportedly greeted with a warm reception at a recent community board meeting.

The property is currently owned by the MTA, which has been discussing the project with developers, according to New York Magazine.
